论文摘要
当用旋转吸收体散射时，旋转超高会产生足够低频率的传入波的扩增。如果旋转体具有足够强的引力场，则可以用来发现质量$ M_B $的新\ emph {bosonic}颗粒，这可能会局限于巨大的粒子并将放大变成指数的生长。结果，可以将初始种子放大，直到在人体周围产生大云为止，这可能会带来许多现象学后果。旋转黑洞是获得此效果的理想候选者，不仅是从它们的吸收和重力特性（因此是限制机制），而且还因为对于质量$ M _ {\ rm bh} $的黑洞，旋转超高功能是有效的$ M_B \ sim \ sim \ sim \ sim \ sim 10^{ - 10} \ left（\ frac {m _ {\ odot}}} {m _ {\ rm bh}}}} \ right）\ rm ev $。广泛的天体物理黑洞质量为探测大质量粒子在很大的范围内很难通过任何其他已知方法检测到的新机会。在此简短的贡献中，我将对其中一些机会发表评论。
Rotational superradiance generates the amplification of incoming waves of sufficiently low frequency when scattered with a rotating absorbing body. This may be used to discover new \emph{bosonic} particles of mass $m_b$ if the rotating body has a sufficiently strong gravitational field, that may confine the massive particle and turn amplification into exponential growth. As a result, the initial seed may be amplified until generating a large cloud around the body, which may have a number of phenomenological consequences. Rotating black holes are perfect candidates to source this effect, not only from their absorbing and gravitational properties (and hence confining mechanism), but also because for black holes of mass $M_{\rm BH}$, rotational superradiance is efficient for $m_b\sim 10^{-10}\left(\frac{M_{\odot}}{M_{\rm BH}}\right)\rm eV$. The wide range of astrophysical black hole masses brings about new opportunities to probe particles of low masses in a large span very hard to detect by any other known method. In this brief contribution I will comment on some of these opportunities.
